Savonet is a set of open-source developments around audio stream generation (ogg/mp3/...), and particularly web-radios using Icecast. It is written in OCaml.
The heart, liquidsoap, is a very powerful and flexible streaming language, abstracting over format, protocol, stream generation, manipulation and output. Allowing arbitrarily deep-nested composition of streams and easy extensibility, it gives you more power than you need for creating an original web-radio. But liquidsoap is still very light and easy to use, in the Unix tradition of many simple strong components working together.

Marionnet is a virtual network laboratory: it allows users to define, configure and run complex computer networks without any need for physical setup. Only a single, possibly even non-networked GNU/Linux host machine is required to simulate a whole Ethernet network complete with computers, routers, hubs, switchs, cables, and more.
Support is also provided for integrating the virtual network with the physical host network.
As Marionnet is meant to be used also by inexperienced people, it features a very intuitive graphical user interface.

Redditwatcher is an Ocaml program that follows the evolution of the scores (up and downvotes, number of comments) of stories appearing on Reddit. Typically, it takes the 50 newest stories and samples their scores at reasonable intervals, writing results into little marshalled files that can be converted to gnuplottable and R-loadable files.
